You can read doc at http://docs.aliyun.com/#/pub/oss/api-reference/multipart-upload&InitiateMultipartUpload

func (*Bucket) List

func (b *Bucket) List(prefix, delim, marker string, max int) (result *ListResp, err error)

List returns information about objects in an bucket.

The prefix parameter limits the response to keys that begin with the specified prefix.

The delim parameter causes the response to group all of the keys that share a common prefix up to the next delimiter in a single entry within the CommonPrefixes field. You can use delimiters to separate a bucket into different groupings of keys, similar to how folders would work.

The marker parameter specifies the key to start with when listing objects in a bucket. OSS lists objects in alphabetical order and will return keys alphabetically greater than the marker.

The max parameter specifies how many keys + common prefixes to return in the response, at most 1000. The default is 100.

For example, given these keys in a bucket:

index.html
index2.html
photos/2006/January/sample.jpg
photos/2006/February/sample2.jpg
photos/2006/February/sample3.jpg
photos/2006/February/sample4.jpg

Listing this bucket with delimiter set to "/" would yield the following result:

&ListResp{
    Name:      "sample-bucket",
    MaxKeys:   1000,
    Delimiter: "/",
    Contents:  []Key{
        {Key: "index.html", "index2.html"},
    },
    CommonPrefixes: []string{
        "photos/",
    },
}

Listing the same bucket with delimiter set to "/" and prefix set to "photos/2006/" would yield the following result:

&ListResp{
    Name:      "sample-bucket",
    MaxKeys:   1000,
    Delimiter: "/",
    Prefix:    "photos/2006/",
    CommonPrefixes: []string{
        "photos/2006/February/",
        "photos/2006/January/",
    },
}

You can read doc at http://docs.aliyun.com/#/pub/oss/api-reference/bucket&GetBucket

func (*Bucket) ListMulti

func (b *Bucket) ListMulti(prefix, delim string) (multis []*Multi, prefixes []string, err error)

ListMulti returns the list of unfinished multipart uploads in b.

The prefix parameter limits the response to keys that begin with the specified prefix. You can use prefixes to separate a bucket into different groupings of keys (to get the feeling of folders, for example).

The delim parameter causes the response to group all of the keys that share a common prefix up to the next delimiter in a single entry within the CommonPrefixes field. You can use delimiters to separate a bucket into different groupings of keys, similar to how folders would work.

Abort deletes an unifinished multipart upload and any previously uploaded parts for it.

After a multipart upload is aborted, no additional parts can be uploaded using it. However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.

NOTE: If the described scenario happens to you, please report back to the goamz authors with details. In the future such retrying should be handled internally, but it's not clear what happens precisely (Is an error returned? Is the issue completely undetectable?).
